Ive been doing a lot of work to get everything fixed on our fire departments M52a2. One issue I have run into is that there seems to be a lot of sludge coming from the drain valve on the air tanks under the drivers step. I spent 2 yrs in the army working on trucks like this and haven't seen anything other than water and rust come out of these tanks. Do I have a serious issue goin on with the air system and if so what do I need to do to correct it? I don't have any manuals for this truck yet and don't have the time to look it up in the online manuals right now so any info would be appreciated.

Sludge, as in water mixed with rust type sludge or oil blow-by coming from the compressor type of sludge?

Oil.

Try cleaning /replacing the air inlet filter, too much inlet restriction increases the engine oil sucked into the compressor.

Worst case you will have to replace the air compressor !! But try the filter first might be he quicker fix!!
